DISCLAIMER:

These photos depict the 13”” Bar Mill after renovation in the 1970’s
which included filling of the Sub-Basement with concrete, a new
floor poured (the Grinding area floor was originally a dirt floor)
and the building was completely repainted. The Milling process
was modernized and machinery relocated during the renovation.
These photos are not indicative of the dusty/dirty conditions of the
1940’s & 1950's. The photos have been staged and are not
representative of the steelworkers daily attire.

BAR MIL] Ls Mill is now producing bars

as advanced in quality as the mill itself is advanced
in technology.

The bars from this mill—initially, carbon and
alloy rounds from 5/8" to 1-15/16" in diameter—are
“quality” in every respect. They consistently meet
the standard commercial rolling tolerances for size
and section. In fact, our standard product normally
is well within these tolerances. The surface quality,
internal structure, and uniformity of size make these
bars second to none. We ship them straight, in neat,
square-end bundles; or in compact coils weighing as
much as 5400 pounds, heaviest in the world.

Altemate horizontal and vertical rolls
severely work the hot steel as they
reduce it in section. This improves
the steel's soundness, mechanical
properties, and surface.

Nine interstand Joopers assure
tension-free rolling. Computer-con-
trolled water boxes maintain proper
bar temperatures.

Entire rolling operation is super-
vised from mill pulpit, the main
monitor and control center of
the mill.

A changeover to roll a different size
bar can be accomplished quickly and
efficiently. Entire stands are moved
in and out of the mill line

As bar speeds along at up to 50 mph,
its diameter is checked continuously.
Bar dimensions are maintained by
computer-directed_micro-adjust
ments of finishing rolls.

Dividing shear makes head and tail
cuts for metallurgical testing, and
cuts bar into cooling-bed lengths or
desired coil weights,
